Ok - I used the manual you sent to troubleshoot my problem, and it turned out it was the logic board. I changed that tonight, and the opener works!!! Unfortunately it will not allow me to program my transmitters.

The new unit is slightly different than the old (there's a light socket in back - Don't know what or if anything else). Is it possible that it's a newer model that won't accept the old transmitters?

For what it's worth, when I try to program them I:

Press and hold the transmitter button

Press the button on the motor

The light (main light) is supposed to flash but never does - I just get three rapid flashes from the small bulb on the back og the unit if I try to use the transmitter.

Did you get a new logic board listed in the manual I link you to. If so that might be the problem. I am not sure, but I think that theyre was a changin in the remote frequencies a couple of years ago. I thank I have seen some things that imply that.

Anyway, if you got the logic board from Sears I would call Sears. Craftsman Tech Support at 1-800-528-5236

If you got it from AAARemtoes or some other source I would cal or email aaremotes.

The board I got was from Sears. They provided that one based upon the model number I provided. I just assumed it was the correct one, but an updated (newer) version. I'll try the tech# you provided. Thanks again.
